Abstract

We explore the microstructural aspects of alloys that affect structural disordering, deformation-induced softening and shear localization during homogeneous deformation, in order to clarify how and why bulk amorphous alloys with different degrees of short-range ordering exhibit different global plasticity. Additional analyses were conducted to derive a simple structural parameter which allows the prediction of the global plasticity of bulk amorphous alloys.
